EXAM — QUESTIONS
• This -question practice exam covers every major concept tested on WGU D265 —
argument structure, deductive and inductive reasoning, logical fallacies, evidence
evaluation, cognitive biases, scientific reasoning, causal and statistical reasoning,
language clarity, and applied critical thinking — each question paired with a clearly
highlighted correct answer and a detailed EXPERT RATIONALE.
• Work through each question independently before checking the answer, study
every EXPERT RATIONALE carefully, and revisit any section where you notice
repeated errors — that targeted repetition is your fastest path to exam readiness.
1. What is the primary function of an argument in critical thinking?
A. To entertain an audience through storytelling
B. To express the speaker's emotions on a topic
C. To provide reasons (premises) in support of a conclusion
D. To persuade using rhetorical devices alone
E. To list facts without drawing any conclusion
✓ Correct Answer: C. To provide reasons (premises) in support of a conclusion
EXPERT RATIONALE: An argument in critical thinking is a structured set of
statements where one or more premises are offered as reasons to justify accepting
a conclusion. The purpose is rational persuasion through logic and evidence, not
emotional appeals or mere rhetoric.
,2. Which of the following best defines a "premise"?
A. The final statement in any written essay
B. A question raised by the arguer
C. A statement offered as a reason to support a conclusion
D. The emotional hook at the start of a speech
E. A definition provided to clarify a term
✓ Correct Answer: C. A statement offered as a reason to support a conclusion
EXPERT RATIONALE: Premises are the supporting statements of an argument.
They supply the evidence or reasons that, if accepted, are meant to justify belief in
the conclusion. They answer the question "Why should I believe the conclusion?"
3. In the argument "All humans are mortal. Socrates is a human. Therefore,
Socrates is mortal," which statement is the conclusion?
A. All humans are mortal
B. Socrates is a human
C. Socrates is mortal
D. All humans and Socrates are mortal
E. Mortality applies to all things
✓ Correct Answer: C. Socrates is mortal
EXPERT RATIONALE: The conclusion is the statement the argument is trying to
establish. It is supported by the two premises: "All humans are mortal" and
"Socrates is a human." The word "therefore" is a classic conclusion indicator.
4. Which of the following words is most commonly used as a CONCLUSION
indicator?
A. Because
,B. Since
C. Given that
D. Therefore
E. Assuming that
✓ Correct Answer: D. Therefore
EXPERT RATIONALE: "Therefore," "thus," "hence," "so," and "consequently" are
conclusion indicators — they signal that what follows is the conclusion of an
argument. "Because," "since," and "given that" are premise indicators — they
introduce the supporting reasons.
5. Which of the following is a PREMISE indicator?
A. Thus
B. Hence
C. Consequently
D. Because
E. Therefore
✓ Correct Answer: D. Because
EXPERT RATIONALE: Premise indicators introduce the reasons that support a
conclusion. Common premise indicators include "because," "since," "for," "given
that," and "as evidenced by." Conclusion indicators include "therefore," "thus,"
"hence," and "consequently."
6. A passage that makes claims but provides no reasons or support for those
claims is best described as:
A. A deductive argument
B. An inductive argument
, C. A non-argument (mere assertion)
D. A sound argument
E. A valid argument
✓ Correct Answer: C. A non-argument (mere assertion)
EXPERT RATIONALE: When someone simply states a position without providing
any supporting premises or reasons, it is a mere assertion — not an argument.
Arguments require at least one premise that offers support for a conclusion.
7. Which of the following is NOT a component of a standard argument?
A. At least one premise
B. A conclusion
C. A claim being supported
D. A rhetorical question with no answer
E. A logical connection between premises and conclusion
✓ Correct Answer: D. A rhetorical question with no answer
EXPERT RATIONALE: Arguments consist of premises and a conclusion, with a
logical relationship between them. Rhetorical questions may appear in persuasive
writing but are not structural components of a formal argument.
8. The logical structure of an argument can best be evaluated by examining:
A. The credibility of the person making the argument
B. The emotional impact of the argument on the audience
C. Whether the premises actually support the conclusion
D. The length and detail of the argument
E. Whether the conclusion is popular or widely accepted
